Sept. 13, 1938. ca. ZANINOVICH DOOR LOCKING BAR Filed Jan. 25, 1938W/AcV/A WITNESSES W INVENTOR Gear-5e zaninovich/ ATTORNEYS PatentedSept. 13, 1938 UNITED states esrss'r @FFWE 3 Claims.

This invention relates to locking bars for doors and particularly to animproved construction for looking a sliding door, an object being toprovide a simple construction which will clamp the door 5 against thebuilding or its frame at both sides when the bar is fully functioning.

Another object of the invention is to provide a locking bar for slidingdoors wherein the bar is pivotally mounted on the door and coacts with10 interlocking members at each side.

A further object of the invention is to provide a locking bar forsliding doors which may be integral throughout or may be made in'two ormore parts and adjustably connected together so 15 as to adapt the barto doors of different sizes.

In the accompanying drawing Fig. l is a'side view of a bar infunctioning position disclosing an embodiment of the invention;

Fig. 3 is an enlarged sectional View through Fig. 1 approximately on theline 33;

Fig. 6 is a fragmentary sectional View through Fig. 5 approximately onthe line 66.

30 Referring to the accompanying drawing by numerals, I indicates theside of a building, as for instance a barn, and 2 a door runway. A door3 is slidingly mounted on the runway 2 so as at one time to cover thedoor opening and at 35 another time to expose the same.

Sliding doors similar to door 3 are old and well known and usuallyrather loosely contact the wall of building I. In the present inventionthere is provided a locking bar 5 which not only looks the 40 door 3closed but causes the same to press against the building I asillustrated particularly in Fig. 3. The locking bar 5 is made from apiece of metal, as for instance steel, and is provided with a stiffeningor reinforced rib 6 extending from one end to the other centrally exceptfor the space I which is reserved for the head of a pivotal bolt 8 whichextends through the aperture 9. Bolt 8, as shown in Fig. 2, extendsthrough a sleeve I which is permanently fixed in the door 3 and 50 whichis preferably made of metal. At one end the bar is formed with anapertured enlargement I I extending from one side of the bar. Thisenlargement is adapted to accommodate one leg of a U-shaped catch l2,which catch is preferably 55 slightly upset at I3 so that it cannot beremoved from its position. The free leg I4 of catch I2 is adapted to beinserted into an eye I5 secured to the wall of building I in any desiredmanner, as for instance by having a bolt extension l6 extendtherethrough and a suitable nut applied. 5 At the opposite end of thebar 5 there is provided a hinge knuckle ll which coacts with knuckles I8on an L-shaped hasp I9. A suitable pintle 20 connects the knucklestogether so that the hasp i9 may swing back and forth as desired. The 10other end of the hasp is provided with a slot 2| which is adapted toreadily slide over an eye 22 secured in place in any suitable manner tothe wall I, as for instance similar to eye I3. The locking bow orshackle 23 of a padlock 24 is adapted to be inserted into the eye, asshown in Fig. 1, when the bar is in full functioning position. Thisprevents either end of the bar from becoming released and also acts withthe catch I2 in holding the door 3 against the wall I.

When it is desired to open the door 3, lock 24 is removed and then thebar 5 is swung upwardly, for instance to the dotted position shown inFig. 1. This upward movement will cause the leg I4 of catch I2 to moveout of the eye I5. 25 The door 3 is then free to slide back and forth onthe runway 2.

Instead of having the bar 5 made to fit only a certain size door, thesame inventive concept could be arranged in a modified structure whichwould fit different size doors.

A modified form of the invention is shown in Fig. 5, in which it will beseen that the bar 5 is formed of a tubular part 25 and a rod part 26.These parts are each provided with apertures, namely, apertures 21 and28. A bolt 8' is adapted to be inserted through any of these aperturesafter they have been properly aligned. It will be understood, however,that the sleeve 1 IE] is preferably central of the door whether the 4door is large or small, and the adjustment of the parts 25 and 26 willtake place before the bolt 8' is applied. Aside from these detailstructures, the construction and arrangement of bar 5' is the same asbar 5 and the same reference numerals will be used.

I claim:

1. A locking structure for a door comprising a bar adapted to extendfrom one side edge to the other side edge of the door, means forpivotally mounting the bar to the door, a catch structure arranged ateach end of the bar body, a fixed eye interlocking with one of saidcatch structures, a second fixed eye interlocking with the second catchstructure, and a padlock shackle extending through said second-mentionedfixed eye.

2. In a sliding door locking bar, a bar body having an aperture arrangedcentrally thereof, a tubular enlargement at one end, a substantiallyU-shaped catch having one leg rotatably mounted in said tubularenlargement, said bar body at the opposite end having a hinge knuckle, alatch formed with a pair of hinge knuckles coacting with thefirst-mentioned hinge knuckle, a pintle for pivotally connecting saidknuckles together, said latch having an eye-receiving slot, a pivotalbolt extending through the central aperture of said bar body and thedoor on which the locking bar is mounted, means coacting with one leg ofsaid U-shaped catch for holding said door in a given position, andauxiliary locking means ing position, a latch structure pivotallyconnected to the opposite end of said bar, a second eye memberinterlocking with said latch structure, and a padlock shackle forpreventing disengagement of said second eye member from said latchstructure.
